IMMERSING DEVICE For. COATING-MACHINES.

Specification of Letters Patent.

Patented Dec. 10,1918.

Application filed March 18, 1918. Serial No. 222,171.

To all whom z'tgmay concern:

Be it known that I, MURRIT M. JEWETT, a citizen of theUnited States,residing at Corning, in the county of Steuben and State of New York,have invented certain new and useful Improvements in Immersing Devicesfor Coating-Machines, of which the following is a specification.

This invention relates to immersing devices for candy coating machines,the primary object being to provide a simple and improved wetting ormoistening device adapted particularly for use in connection with acoating machine-such as that disclosed in the Patent Number 1,239,399,and by the use of which the candies are presented to the coatingmachinery in proper condition to be further acted upon.

A further object of the invention is to provide a simplified andimproved immersing machine which operates upon the candles in suchmanner as not to break, mash or distort the same, which subjects allsides of the article to the moistening fluid, and

which delivers the articles to the coating machinery in the bestpossible condition for the coating operation.

Still further objects reside in constructing a mechanism of thischaracter and for the purposes set forth which is featured by the lackof complicated or intricate parts, which is constructed in such manneras to be easily and quickly cleaned or repaired, which requires but asmall amount of power for its operation, which requires no attentionduring its operation, and which combines efiiciency with simplicity ofconstruction. 5-

With these objects in View, together with. others which will appear asthe description proceeds, the invention resides in the novelconstruction, combination and arrangement of parts, all as will bedescribed more fully hereinafter, illustrated in the drawings, andparticularly pointed out in the claim.

In the drawings Figure 1 is a side elevation, parts in section, of animmersing apparatus constructed in accordance with the invention,

Fig. 2 is a top plan view of the apparatus,

and

Fig. 3 is a vertical sectional view taken substantially upon line 33 ofFig. 1.

The invention consists generally in the arrangement of a relativelyshallow tank having therein a pair of spaced racks or frames, whichprovide between them a channel through which the articles to be coatedare forced. The frames are so shaped as to form a tortuous channelbetween them, and most of thischannelis disposed below the liquid levelwithin the tank. Afeed chute communicates with the channel atone end ofthe tank, while a' discharge chute communicates with the channel attheopposite end, and this discharge chute is adapted to communicate withthe intake end of the coating machine. A plurality of dashers are usedwith the device to causethe caudies to be immersed and carried throughthe channel and delivered to the discharge chute. The discharge chute isarranged in such manner that the candies in traveling to the coatingmachinery will be relieved of superfluousmoisture, so that the candiesare presented to the coating in the best possible condition for thecoating operation.

The machine comprises a relatively shallow tank 40, having an inlet pipe41 com municating therewith, and which is drained by an outlet pipeindicated at 42. The tank may be of any desired size or shape.

Arranged in superimposed relation within the tank are racks 43 and 43,each of which is formed of a plurality of spaced bars disposedlongitudinally ofthe tank. These bars are positioned close together, sothat the articles being treated cannot pass through the same. The spacebetween the superimposed racks constitutes a channel through which thecandies are to pass in the clipping process.

Mounted in suitable bearings 44 above the tank 40, and disposedtransversely of the latter is a shaft 45, which is driven by means of abelt passing over a pulley 47. This shaft carries a rotary dashercomprising radially disposed arms or tines 48, bent rear- ,wardlyattheir extremities as indicated at so constructing the racks, it will beobserved that the greater portion of the passage through which thearticles must pass is tortuous, and is spaced below the liquid levelWithin the tank.

- end therof. The lowest of the superimposed racks extends intotherbottom of this chute, so as to prevent any of the candies reachingthe bottom of the tank. A downwardly inclined chute 51'communicates withthe channel at the opposite end of the tank, and maybe employed fordelivering the articles to the coating machine. It will be observed thatthe upper end of this chute communicates with the channel below theplane of'the shaft which supports the. dasher arms. The discharge chute51 has a false bottom of foraminous fabric or wire mesh 52, and

drain pipes 53 communicate with-the bot-;

tom of the chute to drain liquid therefrom. The pitch or inclination ofthe discharge chute 51 is such as to assure articles of a lighternature, such as marshmallows, against remaining upon the Walls or bottomthereof, and while tumbling down this chute, superfluous moisture willbe shaken from the articles and drained through the pipes 53. Y

In operation, warm water is introduced to the tank 40, and themarshmallows or candies to be treated are delivered to the tank throughthe chute 50. The water level within the tank is above the depressedportion of the upper rack 43, so that the candies must be whollysubmerged in passing through the arcuate or tortuous pass formed betweenthe depressed portions of the said racks. The dasher shaft is rotated inclockwise direction, and the arms 48 which extend between the bars ofboth racks force the candies beneath the surface of the water, throughthe arcuate channel, and then force them into the dicharge chute at theopposite end of the tank. During this operation, the articles are whollysubmerged, and will be sufficiently damp to properly retain the coatingmaterial, to

which they will be' subjected in the coating I operation.

From the foregoing, it is apparent that I have provided an immersing orwetting apparatus which will prove extremely efiicient,

whichis wholly automatic in operation, and which requires no attentionwhatever during its operation. It will be understood that the details ofthe mechanism may be changed or varied according to the material orarticles with which it is desired that the same be in said tank, a pairof arcuate racks in said tank concentric with said drum, beater armsradiating from said drum and extending through both of said racks, andthe outer ends of said arms being curved rearwardly at a pointsubstantially midwaythe distance between the racks, the extremities ofsaid arms lying in a plane in the rear of their respective arms.

In testimony whereof I aflix my signature in presence of two witnesses.
